In the depths of northeastern India, in one of the wettest places on earth, bridges aren't built - they're grown. The living root bridges of Cherrapungee from the roots of the Ficus elastica tree.

This tree produces a series of secondary roots from higher up its trunk and can comfortably perch atop huge boulders along the riverbanks, or even in the middle of the rivers themselves. Via: Atlasobscura.com

The latest concept design from Vincent Callebaut Architects – the Dragonfly – has been designed with the intention of easing the ever-increasing need for ecological and environmental self-sufficiency in the urban cityscape. The proposed development, designed around the Southern bank of Roosevelt Island in New York, follows a vertical farm design.

Spanning 132 floors and 600 vertical meters, the Dragonfly can accommodate 28 different agricultural fields for the production of fruit, vegetables, grains, meat and dairy. A combination of solar and wind power make Belgian architect Vincent Callebaut’s Dragonfly concept %100 self sufficient. Via Vincent Callebaut

Green architecture comes in many forms though lately it seems like these forms are stranger than ever. Urban skyscraper farms? Floating eco-cities? Glowing solar towers? Turbine-driven skyscrapers? Magnetically levitated wind collectors? Where does it end?

Take a look at seven of the most amazing real and conceptual designs currently at the forefront of ecological innovation. These examples push the limits of ecological architecture and contemporary urban design discourse.Via weburbanist
